Postwick Grove, Norfolk 

Editor: This is John Sell Cotman's "Postwick Grove, Norfolk," an undated etching. It feels very detailed despite its size, with a strong contrast between the dark foliage and the open sky. What catches your eye in terms of composition? Curator: The most striking aspect is the artist’s use of line to delineate form and texture. Observe how the density of cross-hatching defines the mass of the trees and creates a sense of depth. Notice the structural similarities between the foliage and the water. Editor: Yes, I see that now. The mirroring effect gives the image an incredible sense of balance. Curator: Precisely. Cotman's strategic deployment of light and shadow further enhances the overall design. The arrangement guides the viewer's eye across the scene. Editor: I never thought about the strategic use of light and shadow in such a small piece. Thank you. Curator: My pleasure. Examining such works in detail offers much in the way of understanding.
